    If The Truck Sits For A Week Or So I Start It And Tranny Fluid Pours Out Of The Dipstick/fill Hole. What Could Cause This, Its Not Over Filled, Also The Tranfercase Has A Habit Of Spewing Fluid Out Of The Breather Hose At Highway Speeds Also Not Overfilled? Any Help Would Be Appreciated.

    I had the same problem with a 400 that I had in my old Firebird. I asked a local tranny shop about it they said that there is plastic piece where the filter mounts that probably has a crack in it and it was sucking air, but I sold the car before I could fix it. You may want to check it out.

    Has the transfercase been clocked or is it in the original position and does your transmission breather have flow ( possibly clogged?)
